运动容器内液体大幅非线性晃动实验研究
Experimental study on large-amplitude nonlinear liquid sloshing in moving container
摘要
Abstract
To analyze nonlinear effect on large-amplitude liquid sloshing,resonance and beat slos-hing phenomena in a rectangular container were experimentally studied.The fluid-filled container was oscillated under lateral harmonic excitation by a vibration generator system.The motions of free surface were observed;and the liquid pressure time histories of a fixed point on the side wall were measured using a pressure sensor.The experimental results show that under the beat condition,re-markable nonlinear characteristics in sloshing are observed,while under the resonance condition,the free surface will soon take the form of violent three-dimensional motions,and the general theoretical model for nonlinear sloshing fails.Similarities and differences between nonlinear theoretical model and real sloshing were discussed by comparing experimental results with numerical ones.关键词
